Description
This deciduous, large-size tree can reach up to 30 m tall and is widely distributed in the eastern half of the US and so appreciated for its ornamental qualities that it became the state tree for Kentucky, Tennessee and Indiana. It grows a straight trunk topped by a pyramidal crown, bright green, lobed leaves, which turn golden yellow during fall and, very showy, fragrant, tulip-shaped, yellowish-green flowers with an orange band around the base, which tend to develop on the upper branches. The wood of Liriodendron tulipifera is occasionally used for furniture, veneers and pulp. It is hardy to USDA Zone 4. For good germination results, seeds require cold stratification for at least 60 days.

Difficult
Liriodendron tulipifera (Tulip Tree) is a large, fast-growing magnolia family member native to eastern North America, prized for its distinctive tulip-shaped flowers and golden fall foliage. Seeds have naturally low viability (5-20%) and require extended cold stratification (60-120 days) followed by warm temperatures to germinate successfully. Germination is often slow and sporadic, requiring patience, but seedlings demonstrate vigorous growth once established.

Growing Tips
Soak seeds for 12-24 hours before starting cold stratification. Place moist seeds in peat moss, sand, or vermiculite in sealed plastic bags in the refrigerator for 60-120 days at 4°C. Keep substrate moist but not saturated throughout. Bring to room temperature (20-22°C) after stratification; germination occurs over 1-2 months and may be irregular. Use large containers as seedlings grow rapidly (up to 60 cm in first year). Do not discard trays prematurely. Provide bright light after germination and maintain consistent moisture.
